It’s a neat website, but it is very America specific.
For example, I’m Australian and I wasn’t taught about slavery or genocide of our native people in high school. Hell, I was taught that the Stolen generation was a misnomer and children were only taken voluntarily or as an act of mercy… I graduated in 2008 so it wasn’t exactly the dark ages. Referring to the planned exterminations of the natives as “battles” and “conflicts” at best was another one. they didn’t even mention the shit that went down in Tasmania.
it’s not just the dumb stuff like food pyramids and taste zones, even in schools today history is being glossed over
